Estimation of Critical Headway at Small Urban Roundabout
Before choosing an intersection project design, an important step is to examine the justification of the construction on the basis of defined criteria. One of the key criteria is the analysis of capacity.

Comparative Analysis of Critical Headway Estimation at Urban Single-Lane Roundabouts
According to models commonly used in practice, the capacity of roundabouts largely depends on the value of critical headway. The value of critical headway depends on the characteristics of vehicles, driving conditions, and geometric characteristics of ...

Predictive modeling of critical headway based on machine learning techniques [PDF]
Due to the impossibility of directly measuring of critical headway, numerous methods and procedures have been developed for its estimation. This paper uses the maximum likelihood method for estimating the same at five roundabouts, and based on the ...

Critical intervals and queue intervals at two-lane roundabouts
Over the past decade, a number of manuals have been developed for rural road roundabouts in the Russian Federation. However, two- and three-lane roundabouts are designed and operated in cities of the Russian Federation do not yet have manuals that take ...

Estimation of critical headway at roundabouts
According to the models which are commonly used in practice, the capacity of roundabouts depends on the value of critical headway. Critical headway size depends on numerous objective factors, primarily on geometric characteristics of the intersection. However, research so far have shown that beside characteristics of the intersection, value of critical

Comparison of Procedures to Estimate Critical Headways at Roundabouts
The capacity analysis of roundabouts in Portugal is mostly done using the UK regression method. Due to its empirical and non-explanatory nature, this method has some limitations, particularly for studying innovative layouts, which has recently motivated research in Portugal into the use of capacity methods based on gap-acceptance theory.

Exploring the uncertainty in capacity estimation at roundabouts
Purpose In gap-acceptance theory the critical and the follow-up headways have a significant role in determining roundabout entry capacities which in turn depend on circulating flow rates under a specified arrival headway distribution.
